ADS4246IRGC25

Analog To Digital Converters (ADC) Overview

The ADS4246IRGC25 is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a sampling rate of 160 MSPS. It functions within the ADS42xx ultralow-power family, utilizing a single 1.8V supply to achieve a total power consumption of 332mW at maximum speed. The device features high dynamic performance, delivering an 88dBc spurious-free dynamic range (SFDR) and 71.4dBFS signal-to-noise ratio (SNR) at a 170MHz input frequency. It incorporates programmable gain up to 6dB for SNR/SFDR trade-offs and includes a DC offset correction loop. Digital outputs are available via a 1.8V parallel CMOS interface or double data rate (DDR) LVDS with programmable swing.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation. Suffixes such as 'CT' indicate tape and reel packaging, while 'CR' denotes reel packaging. Confirm that the component meets RoHS standards and is free of antimony and bromine-based flame retardants as specified in the eco-plan classification.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS4246IRGC25 when 14-bit resolution and 160 MSPS throughput are required. Ensure the design supports a 1.8V analog and digital supply voltage. Verify compatibility with the 0.95V common-mode input voltage requirement. Consider the QFN-64 package dimensions and thermal characteristics for PCB layout planning.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS424x/422x family, which serves as a low-speed variant of the broader ADS42xx series. It is pin-compatible with the previous generation ADS62P49 family, facilitating migration. Key architectural differences include the reduction of the analog supply voltage from 3.3V to 1.8V and the elimination of external reference pins.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4246IRGC25 is pin-compatible with the ADS62P49 family. However, designers must account for the change in analog supply voltage from 3.3V to 1.8V and the removal of external reference requirements when migrating from older devices.
